Correlation of visual quality with satisfaction and function in a normal cohort of pseudophakic patients

摘要

Purpose: To select a normal post-cataract-surgery cohort, determine visual quality parameters, and compare these parameters with self-reported satisfaction and visual function. Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. Design: Retrospective cohort study. Methods: A cohort of pseudophakic patients was selected based on uneventful surgery, good corrected visual acuity (no worse than logMAR 0.02), and lack of ocular complaints or pathology including dry-eye syndrome or posterior capsule opacification. A single-piece high-refractive-index acrylic intraocular lens, age 50 or older, and at least 1 year out from surgery were other inclusion criteria. Testing included logMAR corrected distance visual acuity (CDVA), mesopic 10% contrast logMAR CDVA with and without glare, straylight determination, Rasch-modified National Eye Institute Visual Function questionnaire 11R (NEI VF-11R), custom pseudophakic dysphotopsia survey, and overall satisfaction question. Correlations were determined between these parameters. Results: Of the 2953 patients considered, 70 patients met all criteria, provided consent, and enrolled. Only pseudophakic dysphotopsia (r = -0.60; P<.0001) and the NEI VF-11R (r = -0.44; P<.0001) correlated with overall satisfaction. In addition, pseudophakic dysphotopsia correlated with the NEI VF-11R (r = 0.58; P<.0001). Conclusions: When evaluating a highly controlled population with expected high satisfaction after cataract surgery, pseudophakic dysphotopsia was clearly the only significant dissatisfier. Furthermore, dysphotopsia highly correlated with the NEI VF-11R questionnaire; thus, symptoms of dysphotopsia are also seen to have functional significance. A shortened NEI VFQ survey and satisfaction correlated strongly with the full survey.
